Abstract (en)
[origin: WO2017069676A1] Systems and methods for soft buffer handling with limited memory access bandwidth are provided herein. In some embodiments, a method of operation of a User Equipment (UE) of a cellular communications network includes receiving a retransmission that would require a total number of memory accesses to process that is greater than a memory access bandwidth of a soft buffer of the UE. The method also includes prioritizing which bits should be read from or written to the soft buffer of the UE when processing the retransmission based on the memory access bandwidth, any previously received redundancy versions, and/or a currently received redundancy version. According to some embodiments, this achieves higher system performance than Chase Combining alone while keeping the receiver implementation limitation as low as alternative solutions.
